Despite the fact he has an important role in the film, Elias Koteas who plays Hank is not credited.

In the film's title and in the credits, the letters I and O in people's names are replaced with the numerals 1 and 0.

After the credits finish, there is a scene with Victor using a camcorder in a supermarket. He pulls a cart along with a string and films it moving "by itself", he pushes it and then follows it filming, he walks up to various products and tosses them into the cart, filming everything from various angles. This is followed by the "completed" shot of Simone, casually making her shopping selections. Finally, we see the Echo Magazine reporter, watching Simone shopping on TV. He sighs, and says, "She likes chicken pot pie. Just like me."

In the video/DVD release, the "Simone as herself" gags in the closing credits have been removed and replaced with proper credit for the actress.

In the theatrical version, Rachel Roberts is uncredited. Closing credits include "Introducing Simone as herself" and the credits list Simone as played by "herself". However, she is included in the "Simone wishes to thank the following for their contribution to the making of Simone" section.
